About Base64

Encode text for data URLs, tokens, and ASCII-safe transport, or decode Base64 back to readable UTF-8. Remember: Base64 is encoding, not encryption - anyone can reverse it.

Frequently asked questions

Yes. Text is encoded and decoded using UTF-8 so non-ASCII characters are handled correctly.

No. Base64 is an encoding scheme for representing binary data as text. It is not encryption and should not be used for secrecy.
